Definitions

  • the invention relates to a toothbrush with a brush head and a handle formed thereon, the brush head having a protruding, conical or concave tip.
  • a toothbrush of this type is known from DE-PS 889 135.
  • the one-piece brush head is exchangeably fastened to the handle piece with the aid of a bayonet lock in order to enable frequent replacement.
  • the bristles of the brush head which rise sharply towards the center, improve and facilitate tooth cleaning compared to conventional toothbrushes, the bristles of which end in one plane, an optimal mode of operation cannot be achieved.
  • the few bristles arranged in the middle of the brush head are in fact worn or bent over in a relatively short time, so that cleaning of the chewing or tooth furrows and the interdental spaces is no longer possible even after a short use.
  • the object of the invention is therefore to provide a toothbrush which is designed in accordance with the anatomy of a bit and can be used universally for cleaning the interdental spaces as well as the dentures with simple handling.
  • the aim is to ensure that the part of the brush head which forms the tip can be adapted automatically and easily to different individual tooth space depths, if necessary, and easily replaced, and can also be readjusted in the event of wear.
  • universal use should always ensure good handling and an even distribution of force.
  • this is achieved in a toothbrush of the aforementioned type in that the bristles of the brush head which form the tip are mounted in a separate bristle holder which is inserted in the brush head and which is resilient and / or adjustable in height and / or exchangeably held.
  • the bristle holder can be held axially adjustable in a threaded hole machined into the brush head, but it is also possible to hold the bristle holder axially adjustable in the brush head against the force of a spring.
  • the bristle holder can also be displaceably guided against the force of a spring, preferably in an interchangeably and vertically adjustable sleeve, in a recess incorporated in the brush head, or the spring cooperating with the bristle holder can be supported by a pad or on the brush head, preferably on the rear side thereof an insert made of a resilient material, for example rubber, arranged therein can be formed by a gas cushion or the like locked in a chamber.
  • a spring preferably in an interchangeably and vertically adjustable sleeve, in a recess incorporated in the brush head
  • the spring cooperating with the bristle holder can be supported by a pad or on the brush head, preferably on the rear side thereof an insert made of a resilient material, for example rubber, arranged therein can be formed by a gas cushion or the like locked in a chamber.
  • the bristle carrier In the case of a toothbrush provided with a rotating body as a brush head, it is appropriate to insert the bristle carrier centrally into it.
  • the bristle carrier In the case of a toothbrush provided with a rectangular brush head, on the other hand, the bristle carrier should be arranged centrally in its front region, or two or more bristle heads should be arranged one behind the other in the axial direction with a spacing approximately corresponding to a tooth width.
  • the brush head can consist of a ring rotatably mounted in the head of the handle and the brush holder which passes centrally through it, which is connected in a rotationally fixed manner to the ring and can be exchanged in the head of the handle and in its vertical position is held adjustable.
  • the bristle carrier should have a guide piece which is provided with an outer jacket surface which is designed as a polygon or is provided with a driving surface or the like and which is guided in a continuous assigned recess of the ring in the axial direction.
  • bristle carrier on the side opposite the bristles with a threaded attachment which can be screwed into a threaded hole machined into the head of the handle.
  • the bristle carrier can consist of one part, but it is also possible to interchangeably insert the bristles of the bristle carrier into the guide piece.
  • the brush head In order to allow the bristles to act on the teeth with an almost uniformly high force everywhere, the brush head should be inclined to the longitudinal axis of the handle at an angle ⁇ of 10 to 25 °, preferably at an angle ⁇ of 15 ° to the handle.
  • the bristles of the brush head or of the ring and of the bristle carrier should each be arranged in tufts, and the flexibility of the bristles of the bristle carrier can be made harder than the bristles of the bristle head or ring.
  • the bristles of the brush head that form the tips are attached to a separate bristle carrier, which can be held in a resilient, exchangeable and / or height-adjustable manner, the bristle carrier can be individually adjusted to the respective interdental space depth, which is usually more pronounced in older patients due to the loss of teeth is to be adapted than in younger people, or the latter can adapt itself to different depths of the groove.
  • the tips of the bristles can thus reach the deepest points of the interdental spaces, without pressure, in order to remove deposits.
  • the wear on the bristles of the bristle holder can be compensated for over a longer period of time by adjustment, and the bristle holder is easy to replace when worn, so that there is a long service life without the cleaning intensity suffering from prolonged use.
  • the brush head can be arranged at an angle to the handle and this can be provided with two finger bearings, good handling and uniform power transmission are guaranteed.
  • the anatomically shaped toothbrush shown in FIG. 1 and designated 1 consists of a rotationally symmetrical brush head 11 and a handle 12 attached to it.
  • the brush head 11 is provided with a central tip 16 in order to be able to thoroughly clean both chewing channels and interdental spaces.
  • the tip 16 of the brush head 11 is formed by bristles 15 which are attached to a separate bristle carrier 14 used in the head 12 'of the handle 12.
  • a threaded bore 17 is machined into the head 12 ', into which the bristle carrier 14, which is provided on the back with a key opening 18, is screwed.
  • Finger bearings 27 and 29 formed by webs 28 and 30 are integrally formed on the handle 12 on the inside and outside thereof. This ensures good transmission and even distribution of the force applied to the teeth to be cleaned.
  • the bristle carrier 14 ' is held on the head 12' of the handle 12 by means of a compression spring 19.
  • the spring 19 is equipped with an extension in the form of a pin 21, on which the bristle carrier 14 'is interchangeably attached.
  • the tip 16 of the bristles 15 thus automatically adapts to different depths of the groove or interdental spaces, so that excessive pressure, due to the u. U. Injuries can be avoided.
  • the compression spring 19 is also easy to clean.
  • the bristle carrier 14 ' is replaceably attached to a bolt 22 which is axially displaceably guided in the bore 20' of the head 12 '.
  • the tip 23 of the bolt 22 engages in a corresponding recess of the bristle carrier 14 '.
  • a compression spring 19' which is supported on the head 12 'and a plate 23 connected to the bolt 22'. If the contact pressure is too strong, the bristle carrier 14 'and thus the tip 16 of the brush head 11 can dodge.
  • the bolt 22, on which the bristle carrier 14 'is interchangeably attached by means of a plate 24 which is glued or welded, held on the head 12' of the handle 12.
  • the plate 24 is provided with a central through hole 25.
  • a compression spring 19 ' is also supported, which holds the bristle carrier 14' in the front end position.
  • the bristle carrier 14 'can thus evade not only in the axial direction, but also laterally when the contact pressure is too high.
  • Figures 5 and 6 show that toothbrushes with a rectangular brush head 11 'can be provided with replaceable and adjustable bristle carriers 14 and 14'.
  • the bristle carrier 14 is arranged centrally in the front region of the brush head 11 ', in the embodiment according to Figure 6, a plurality of bristle carriers 14 are provided, which are arranged one behind the other in the longitudinal direction with an approximately corresponding tooth width distance.
  • the anatomically shaped toothbrush shown in Figures 7 and 8 and designated 1 ' also consists of a brush head 31, a handle 32 and a bristle carrier 34' inserted in its head 32 ', the bristles 35 together with the other bristles 33 having a concave curved surface of revolution Form 40 with a tip 36.
  • FIGS. 12 and 13 it is possible, as shown in FIGS. 12 and 13, to clean both the chewing grooves 3 of the teeth 2 and the spaces 4 between the teeth 2 thoroughly.
  • the bristle carrier 34 is in turn arranged to be adjustable in the axial direction.
  • a ring 37 is rotatably inserted into a recess 38 incorporated into the head piece 32 'of the grip piece 32, which ring is connected in a rotationally fixed manner to the bristle carrier 34.
  • a polygonal guide piece 42 is formed on the bristle carrier 34, which extends through a recess 41 of the ring 37, as well as a threaded pin 43 and a threaded bore 39 is machined into the head piece 32 'of the grip piece 32 centrally to the trough 38.
  • the mounting of the ring 37 in the head piece 32 ' is accomplished by means of a molded-on detent projection 44 which engages over the ring 37 from the outside.
  • the bristle carrier 34 By rotating the ring 37, the bristle carrier 34 can be adjusted in its vertical position since it is connected to the ring 32 in a rotationally fixed manner but is screwed into the threaded bore 39. If the bristles 35 of the bristle carrier 34 arranged in tufts wear out, they can thus be adjusted in a simple manner, so that pronounced interdental spaces or chewing grooves can always be cleaned by the bristles 35 of the bristle carrier 34 forming the tip 36. A worn bristle holder can also be replaced in a short time.
  • the brush head 31 is arranged inclined at an angle ⁇ of 15 ° to the longitudinal axis A of the grip piece 32, as a result of which the bristles 33 and 34 are approximately at right angles to the tooth surfaces to be cleaned.
  • two finger bearings 47 and 49 are attached to the handle 32 on its inside and outside, which are formed by integrally formed webs 48 and 50, respectively. In this way, a uniform pressure can be exerted both when cleaning the chewing grooves 3 and when cleaning the interdental spaces 4.
  • the bristle carrier 34 can consist of one part according to FIG. 9, but it is also possible, as shown in FIG. 10, to plug the bristles 35 'of the bristle carrier 34 onto the guide piece 42'.
  • the bristles 33 inserted into the ring 37 in tufts, as can be seen in FIG. 11, can be made softer in their flexibility than the bristles 35 of the bristle carrier 34 in order to achieve a different cleaning effect in this way and by softer ones in the ring 37 arranged bristles 33 to avoid injury to the gums.
  • the toothbrush 51 shown in FIG. 14 has a rectangular brush head 61 attached to a handle 62, in which bristles 63 and a bristle carrier 64, the bristles 65 of which in turn form a tip 66, are inserted.
  • the bristle carrier 64 is, as can be seen in particular in FIG. 15, slidably arranged in a sleeve 68 which is screwed into a threaded bore 67 provided in the brush head 61 by means of an external thread 69.
  • a compression spring 70 arranged in the sleeve 68, so that the bristle carrier 64 is not only held vertically adjustable and exchangeable, but is also resiliently mounted.
  • the tip 66 of the bristle carrier 64 can thus automatically adapt to the particular circumstances of a bit.
  • bristles 83 can be provided between the individual bristle carriers 84, which are to be arranged at a distance from one another which corresponds approximately to a tooth width.
  • the bristle carriers 84 which are inserted in bores 87, are resiliently held in the longitudinal direction in these configurations.
  • individual caps 88 or a support 89 made of rubber or a similar resilient material are used for this purpose, which are attached to the back of the brush head 82.
  • an insert 91 made of rubber or an elastically deformable material can also be used in a chamber 90, or the chamber 90 can hold a gas cushion.
  • electrically operated toothbrushes can also be designed in accordance with one of the configurations shown in FIGS. 1 to 17.
